Lesson: Interactions of Electromagnetic Waves with Matter Physics
In this lesson, we will learn how to describe the effects of different types of electromagnetic waves on matter, including their effects on the human body.
One or more of the following types of electromagnetic radiation contain at least some wavelengths that are ionizing. Which of these types can or must be ionizing?
One or more of the following statements correctly describe the properties of electromagnetic radiation that are required for effective transmission through solid plastic cable cores that have a plastic coating of a higher density. Which statements are correct?
- The radiation must be weakly absorbed by plastic.
- The radiation must be strongly absorbed by plastic.
- The critical angle for the radiation at the boundary between the plastic of the cores must be large.
- The critical angle for the radiation at the boundary between the plastic of the cores must be small.
Which of the following types of electromagnetic radiation has the strongest interaction with matter?
